I tried to copy the same code from the lesson, but it still shows an error

//
//  RecipieFeaturedView.swift
//  Recipe List App
//
//  Created by Sam Grover on 12/06/22.

import SwiftUI

struct RecipieFeaturedView: View {
    @EnvironmentObject var model: RecipeModel
    var body: some View {
        
        TabView{
            ForEach(0..<model.recipes.count){
                index in
                if model.recipes[index].featured == true{
                    Rectangle()
                }
            }.tabViewStyle(PageTabViewStyle(indexDisplayMode: .always))
        }
    }
}

struct RecipieFeaturedView_Previews: PreviewProvider {
    static var previews: some View {
        RecipieFeaturedView().environmentObject(RecipeModel())
    }
}

You need to add id: \.self these days, re:


ForEach (0..<model.recipes.count, id: \.self) { index in
   …
}

It wasn’t necessary until a few months ago, but now it is.

Thank you! I had the same problem.

Also noted that’s a warning, not an error, so it isn’t “critical” yet to fix, but it could be in the future
